And you have it set up correctly as shown here. https://www.eventideaudio.com/support/downloads/setting-prepost-routing-options-h9 Also for everyone else, the H9 is designed for -10dB input levels. Which is guitar levels. Most amps especially tube amps are +4 to +6 dB and will overload the H9 input. Now if the loop has adjustable gain. Settings you are good to go.

Thanks, but I’ve already read it 10 times.

I know the line level issue, but Koch designed their amp for -10dB input so that it could handle guitar pedals. Yes, they’re smart 🙂

I repeat that without using the pre/post function, the h9 alone in the fx loop works perfectly.
